Has the UK government imposed new visa rules similar to the US, especially regarding post-study work visas for a Bachelor's/Master's?

Yes, the UK has recently updated its post-study work visa rules, in a way similar to recent US policy changes.

- From 1 January 2027, the UK Graduate Route visa for international bachelor’s and master’s graduates will be reduced from 2 years to 18 months.
- PhD graduates will still receive a 3-year post-study work period.
- If you apply before 31 December 2026, you remain eligible for the current 2-year post-study stay.

If you want the longer post-study work period in the UK, applying before the end of 2026 is important.
